Joe: As I recall, there was a thread about modifying rudders on the old website. Is that archived and retrievable someway. I know you are the website "guru" and may be able to help. After watching my 10 year old son drive through the PHRF fleet in light air, I've seen his potential and decided to go ahead and make or modify an extra rudder to be balanced.
Any body out there have an old rudder they would be willing to sell?!
